The Indonesian Geographers Association Urban Socio-Economic Variables and Intra-Urban Trips

Abstract This study examines the relative influence of socio-economic variables of urban centers on intra-city trip generation. Data were collected on sixteen socio-economic variables and household trip generation in fourteen urban centers of the state. The nature and degree of relationships between socio-economic variables and trips generated were established through simple bivariate correlation technique. Multiple regression analysis was used to explain variables that predict trips generated. The principal component analysis was used to resolve observed collinearity problem in re-gression analysis.There is a strong significant positive correlation between trip generated and 13 out of sixteen socio-eco-nomic variables. The principal component analysis on the socio-economic variables produced two components: social and commercial component and industrial development component.The two components explain 58.68 % of variation in intra-urban trips generated (F=7.830, P≤0.50), (F=13.982, P≤0.50). The industrial development component does not provide significant explanation.The study emphasizes the need for proper planning and effective monitoring of develop-ing of socio-economic variables in cities because of their critical influence on trip generation. Abstrak Penelitian ini menguji pengaruh relatif variabel sosio-ekonomi dari pusat-pusat perkotaan terhadap munculnya perjalanan intra-perkotaan. Data yang digunakan berupa enam belas variabel sosio-ekonomi dan data perjalanan intra-perkotaan oleh rumah tangga di empat belas pusat-pusat perkotaan. Sifat dan derajat hubungan antara variabel sosio-eko-nomi dan jarak perjalanan yang dihasilkan dianalisis melalui teknik korelasi bivariat sederhana. Analisis regresi bergand
